Full disclosure I am not hugely familiar with the Swift SDK But it seems like you should be able to get something working with a bit of effort High level 1 Streaming via the proxy relies on Server Sent Events You will need some code that lives alongside your SDK to subscribe to your steaming endpoint There is a GET endpoint on the proxy for subscribing using SSE of the form `https lt proxyurl gt sub sdk abcd1234` 2 On streaming updates you would need to manually update the SDK with the latest features I believe you d use the SDK s public method `featuresFetchedSuccessfully features isRemote ` to pass down the latest features

Some info I found about using event source in Swift I think your implementation would be much simpler though no passed headers only one type of callback <https nickarner com notes working with server sent events in swift november 16 2021 >
